Question 98Electricity/Electronics - 1st Asst/Chief70% to pass
An electrical component is connected across a 120 volt 60 hertz AC supply. What is the current drawn by the component if the impedance is 200 ohms?
AI Explanation
The correct answer is B) 0.60 amperes.
To calculate the current drawn by the component, we can use Ohm's law, which states that the current (I) is equal to the voltage (V) divided by the impedance (Z). In this case, the voltage is 120 volts and the impedance is 200 ohms. Plugging these values into the formula, we get:
I = V / Z
I = 120 volts / 200 ohms
I = 0.60 amperes
The other answer choices are incorrect because:
A) 0.01 amperes is too low.
C) 1.67 amperes is too high.
D) 100 amperes is significantly too high.
